Well, quite literally so! Get nitrogen for your car tyres and feel the difference for yourself. I think its not available in hyderabad still, but one of my friends from bangalore told me regarding this.
In Banaglore, you can get nitrogen for your tyres at the HP petrol pump on (Old) Airport Road itseems. And, he told me the exact address. . He said, "If you’re coming from Marathalli, then look for a Pizza Hut on your left, you'll find this place immediately after the crossing." But, i hope hyderabad also provides this facility.
